Machining
The machinability rate of ASTM A36 is estimated to be 72%, and the average surface cutting feed of ASTM A36 is 120 ft/min. Machining of ASTM A36 steel is not as easy as that of AISI 1018 steel.
Welding
ASTM A36 steel is easy to weld using any type of welding methods, and the welds and joints so formed are of excellent quality.
Heat Treatment
Any standard carburizing and hardening methods of AISI 1018 steel is suitable for ASTM A36.
ASTM A36 is subjected to the following processes:
Normalizing at 899°C – 954°C (1650°F-1750°F)
Annealing at 843°C – 871°C(1550°F-1600°F)
Stress relieving at 677°C – 927°C(1250°F-1700°F)
Carburizing at 899°C – 927°C (1650°F-1700°F)
Hardening at 788°C – 816°C(1450°F-1500°F)
Applications
ASTM A36 steel has the following applications:
It is used in bolted, riveted or welded construction of bridges, buildings and oil rigs.
It is used in forming tanks, bins, bearing plates, fixtures, rings, templates, jigs, sprockets, cams, gears, base plates, forgings, ornamental works, stakes, brackets, automotive and agricultural equipment, frames, machinery parts.
It is used for various parts obtained by flame cutting such as in parking garages, walkways, boat landing ramps and trenches.
